Is is possible for me to make my own tip for my soldering iron?

Question

I was hoping to just make a smaller one, because the one I have now is bigger and not very precise. What material is the tip usually made out of?

Answer 1

The tip is probably steel.  That said, why not just grind down the one you have?

Answer 2

I knew an electrician/electrical engineer who recommend using solid copper wire. Find a piece just small enough to fit into the sockets on the iron. You can bend it into any shape you want, hammer it flat, file it to a point, whatever.
